Which of the following fluids is not secreted by stomach?

Options

A. Bile juice
B. Hydrochloric acid
C. Pepsinogen
D. Mucus

Answer

To determine which fluid is not secreted by the stomach, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Secretions of the Stomach**:
- The stomach primarily secretes gastric juice, which is composed of several components.

2. **Identify the Components of Gastric Juice**:
- Gastric juice is secreted by different types of gastric cells:
- **Mucous Cells**: Secrete mucus to protect the stomach lining.
- **G-Cells**: Secrete gastrin, a hormone that stimulates gastric acid secretion.
- **Parietal Cells**: Secrete hydrochloric acid (HCl) and intrinsic factor.
- **Chief Cells**: Secrete pepsinogen, which is converted into pepsin, a protein-digesting enzyme.

3. **List Common Fluids Associated with Digestion**:
- Common digestive fluids include:
- Gastric juice (includes HCl, pepsinogen, and mucus)
- Bile (produced by the liver)
- Pancreatic juice (produced by the pancreas)

4. **Analyze the Options**:
- If the question provides options, we need to identify which one is not secreted by the stomach.
- Based on our understanding, bile is produced by the liver and is not secreted by the stomach.

5. **Conclusion**:
- The fluid that is not secreted by the stomach is **bile**.

### Final Answer:
The fluid that is not secreted by the stomach is **bile**.
